Where at the back of the motor? The freeze plugs are on the sides of the Block. If it's coming out up top - towards the distributor, then you need a new intake manifold gasket. The temp you reached may have caused other damage - maybe not. You need to fix where it's leaking and then check compression. AND if it is a freeze plug, then it probably has enough galvanic corrosion to destroy the head gaskets so checking compression and/or doing a leakdown test isn't a bad idea.

water
Remember, there are 2 more freeze plugs at the back of the block just above the crankshaft.
I would not suspect those, though, I would go for the hoses towards the back of the block spraying the water. heater hoses, etc. hard to dislodge a freeze plug.........
If you have water out the back underneath, I also would suggest you look to see if yoiu have the factory water/oil cooler next to the oil filter.
Those hoses go unchanged for years until they either start to leak or burst.

I had a 90 Firebird and the same thing happened, pored out the back. Had to get it done fast as it was the wife’s car and had a shop do it. It was the freeze plugs on the rear of the engine.
Thought it was a really strange problem to happen in that location, it always bothered me. They had to pull the engine.
